The special, narrated by NBC/MSNBC news anchor Lester Holt, focuses on the Dec. 5, 1945, disappearance of five Navy Avenger torpedo bombers and a Mariner rescue plane sent to find them as part of the largest search in maritime history.

“The disappearance of Flight 19 and the Mariner rescue plane remains to this day one of the world's most enduring and compelling mysteries," USA Network and Sci Fi president Bonnie Hammer said in a prepared statement. “With The Bermuda Triangle: Startling New Secrets, we at the Sci Fi Channel partnered with our colleagues at NBC News in an effort to shed some new light on this extraordinary event.”
